Jerry Kelly Heating & Air Conditioning Heating & Air Conditioning in Saint Peters, MO

Rated Excellent
Rated Excellent from 11 reviews
After working in the heating and cooling business for twelve years, Jerry Kelly and his wife Janet opened their own company in 1977. They started Jerry Kelly Heating and Air Conditioning in a white and green brick building in the historic Frenchtown district of Saint Charles, Missouri. With five technicians and a lot of used trucks, Jerry and his team forged a tradition that still stands to this day, "We don't just say '24-hour service', we follow through."

This same building remains our home, and we've added our custom duct fabrication facility down the street. Jerry is now retired, but Jerry's daughter Jill and her husband Steve Miles are involved with every aspect of the business. Jerry and Janet Kelly are enjoying their retirement, but still play important roles in the company and the St. Charles community. And three of the five original technicians remain a part of our 50-plus team of managers, install techs, service techs, customer service representatives, dispatchers, and comfort specialists.

  Testimonial by Michelle Fortner
Had a great experience with Jerry Kelly. I was able to get a service appointment the same day I called. John was a great help with figuring out what was wrong with the A/C. When it looked more and more like a new unit was the best option, John had James here quickly to go over options and get things scheduled. Both were great at explaining how and why things were done. Doug and Alex were here right on time for my install and were nothing but professional. Both showed me what they did and explained why. I would definitely call them for any future needs, but they did such a great job, I don't think I'll have any for awhile.

After a bad freon leak in the old A.C., it was time to purchase a whole new heat and A.C. system. Ronan from Jerry Kelly came out to do the diagnosis and set up the sales order and financing. He was very knowledgeable and took the extra time to make sure ha had every measurement and detail accounted for for an easy install.

The installers were David and Ben and they were also fantastic. The install was quick, very professional and they left the work area looking better than when they arrived. They made sure everything from the hardware, filters, thermostat, warranty, etc. was explained and that there were no questions.

Thank you!

Tons of good advice, very knowledgeable! Curtis and Keith showed me exactly what was wrong with my furnace and even went the extra mile to explain all the steps they took to fix it. I'll definitely be calling Jerry Kelly again for anything I need.

Graham arrived on time and went above and beyond to troubleshoot our furnace problem, locate the parts and materials and completed the repair quickly. Graham was knowledgeable and friendly. We would be happy to have him back in our home for any further issues. Thank you Graham and Jerry Kelly.

Outside unit had quit. Ryan arrived promptly at the scheduled time and immediately determined the cause. After replacing some components and testing to ensure the refrigerant was okay, the system was back up in less than an hour. Have used Jerry Kelly's staff for over 15-years and continue to do so,

I called when my AC went out to have a new unit installed. Jose came to the house within an hour of me calling to give me a quote. Brandyn and Tyler showed up and did an outstanding job at installing everything! The new install looks extremely professional and done correctly. They made sure the system was up and running, and walked me through everything.
  Testimonial by Heide Plaster
John Cody was awesome!! He came to check on a loud start up sound that my new air conditioner was making. He checked everything outside as well as inside. He made a few adjustments inside and I am happy to report that I do not hear that horrible sound. Thank you John for your fast, thorough, and, most of all, your friendly service.
  Testimonial by Jim Bava
The technician, Kory, did a great job explaining everything to me and made sure my furnaces were tuned up properly for the winter. He also told me about a part that should be replaced in the future but did not pressure me to purchase the part now. The price charged was fair and reasonable for the service provided. I was appreciative that his work van was clearly marked and that he was neat and professional. I will use them again and do recommend them for your heating and AC questions.
  Testimonial by Sam Swofford
Korey T. came out to diagnose our AC never stopping. It was 59 degrees in our house. We called at 6:15 on a Monday. Korey was here by 6:45. He tested the compressor and the circuit board and finally diagnosed the problem as the thermostat. It was a Jerry Kelly thermostat with a lifetime warranty. He replaced it with a new one and since Jerry Kelly is a great company that stands by their work, there was no charge for the visit since it was caused by their product. We are JK customers for life.
  Testimonial by Joe Gustafson
Our air conditioner that we purchased from Jerry Kelley about 5 years ago was functioning fine until today. We called for service earlier today and they sent Ryan to the rescue. He is very friendly and explained in detail what the process would be to diagnose the problem. He is very professional and we would highly recommend him to others. Thank you Ryan for your assistance.
  Testimonial by John Patrylo
Everyone on the phone was very polite when making my appointment and our service technician Tyler P. was very courteous and did an excellant job getting our furnace ready for the winter. Went over everything that he did showed me what needed to be done and got everything done in a timely manner. We'll always go with Jerry Kelly with all our AC and Furnace needs.
